Attachment for guard plates in weaving machines

Abstract

Attachment for guard plates in weaving machines, characterized in that it essentially consists of at least three couplings (3), each formed by a cylinder-shaped element (4) which is attached to the guard plate (1), and a seating (5) which is mounted to the frame (2) of the weaving machine and which closes flexibly round the cylinder-shaped element (4), whereby at least one coupling (3) is situated at the top of the guard plate (1), whose cylinder-shaped element (4) has a vertical or almost vertical axis (6), and whereby at least two couplings (3) are situated at the bottom of the guard plate (1), whose cylinder-shaped elements (4) have horizontal or almost horizontal axes (7) in line with each other.

We claim: 
     
       1. An attachment for guard plates in weaving machines, comprising at least three couplings, each formed by a cylinder-shaped element which is attached to a guard plate, and corresponding seating means mounted to a frame of the weaving machine for closing flexibly around the cylinder-shaped element when the guard plate is coupled to the frame, wherein at least one of said couplings is situated at a top of the guard plate, the cylinder-shaped element of said top coupling having a substantially vertical axis, and wherein at least two of said couplings are situated at a bottom of the guard plate, the cylinder-shaped elements of said bottom couplings having substantially horizontal axes in line with each other. 
     
     
       2. An attachment as claimed in claim 1, wherein the number of said couplings is four, two of said couplings are situated at the bottom of the guard plate, and two of said couplings are situated at the top of the guard plate. 
     
     
       3. An attachment as claimed in claim 1, wherein at least one of said cylinder-shaped elements has an end which is attached to a support on said guard plate. 
     
     
       4. An attachment as claimed in claim 1, wherein at least one of said cylinder-shaped elements is made of dampening material. 
     
     
       5. An attachment as claimed in claim 4, wherein at least one of said cylinder-shaped elements is made of synthetic material. 
     
     
       6. An attachment as claimed in claim 1, wherein at least one of said seating means comprises two flexible elements mounted adjacent one another and having bent parts which close about the corresponding cylinder-shaped element, said flexible elements further having means including widening parts for facilitating coupling of a cylinder-shaped element to said flexible elements. 
     
     
       7. An attachment as claimed in claim 6, wherein the flexible elements are leaf springs. 
     
     
       8. An attachment as claimed in claim 7, wherein said leaf springs are each made in one piece and have a U-shape. 
     
     
       9. An attachment as claimed in claim 8, wherein the U-shaped leaf springs are each mounted by means of a bolt and a clamp, and wherein said clamp is engaged by and thereby forms a stop for the cylinder-shaped element when said cylinder-shaped element is coupled with said seating means. 
     
     
       10. An attachment as claimed in claim 1, further comprising a supplementary lock including hooking means for connecting the guard plate with the frame upon turning of the hooking means. 
     
     
       11. An attachment as claimed in claim 10, further comprising detachable connection means between the top of the guard plate and the frame of the weaving machine for allowing the guard plate to open over a predetermined angle. 
     
     
       12. An attachment as claimed in claim 1, wherein the bottom couplings permit the guard plate to be turned around said horizontal axes.
